Mm, did a bunch of quick research and it turns out that the force of a meteor varies greatly. You probably should work with something more specific, cause meteors go from apparently causing the ice age to just bruising someone.

Meteors are just rocks that go so fast they catch fire. Some of them even never touch ground, completely vaporizing through the atmosphere. And yes, we're speaking of supersonic speeds. So start thinking in terms of "space rocket" at the lowest, and "experimental railgun" at the highest.
